Park approximately 400 m past the Refuge de l’Agnel, continuing the ascent towards the Col Agnel. There is a large, designated car park.
(S/E) Cross the Col Agnel road and take the south-facing path that passes beneath the dry toilets.
(1) Cross the Riou Long (the upstream section of the Aigue Agnelle). At the ‘Sentier déambulatoire’ sign, head towards the Col de Chamoussière by taking theGR®®58, marked in red and white. Continue along this path until you reach the Col de Chamoussière.
(2) Turn left onto the ridge to reach the Pic de Caramantran. Note: there are several cairn-marked paths leading easily to the summit, marked by a cairn and a small stone bearing the inscription ‘Pic de Caramantran 3025 m’.
(3) Begin your descent by following the ridge for around 50 metres, then take a moment to assess the route ahead. Several paths branch off; stay on the highest one, which leads to a cairn with a green flag and a plaque reading ‘Lollo in vetta’.
(4) Here, follow the yellowPR®® markings to easily reach the Col de Saint-Véran by following the French-Italian border.
(5) Continue along the border towards Rocca Bianca until you see a cairn-marked path branching off to your right, leading down towards the lakes.
(6) Leave the ridge and take this path, following the cairns. You’ll first pass close to Lac Blanchet Supérieur.
(7) Walk alongside it, then continue downhill to reach Lac Blanchet Inférieur.
(8) Go round it on the left and you’ll soon reach the yellow-marked path leading to the Col Blanchet.
(9) Leave the path leading to the pass on your left and continue downhill to the right. You will then reach Lac de la Blanche and the refuge of the same name.
(10) Head towards the old refuge; a sign for Refuge de la Blanche, Alt 2499 m, points the way to Col de Chamoussière.
(11) Cross the Aigue Blanche. Begin the ascent across the mountain pasture. Join theGR®®58shortly before the pass. Turn right onto it to return to the Col de Chamoussière, which you passed on the way out.
(2) Follow the route taken on the way there in the opposite direction; after the descent, you will reach the large car park at Col Agnel (S/E).
